Abstract:
... Subalpine shrubs are undergoing, or have experienced profound changes by force of recent climate anomalies, such as the alteration in temporal niche of phenophases and the dynamic interaction with ambient conditions. As cold biomes in high-altitude ecoregions, they have drawn a growing concern of the potential vulnerability to current and future climate change. In this study, we retrieved the time ...

Abstract:
... Climate change is intensifying the hydrologic cycle and is expected to increase the frequency of extreme wet and dry years. Beyond precipitation amount, extreme wet and dry years may differ in other ways, such as the number of precipitation events, event size, and the time between events. We assessed 1614 long‐term (100 year) precipitation records from around the world to identify key attributes o ...

Abstract:
... The Neotropical ecoregion has been an important place of avian diversification where dispersal and allopatric events coupled with periods of active orogeny and climate change (Late Pliocene–Pleistocene) have shaped the biogeography of the region. In the Neotropics, avian population structure has been sculpted not only by geographical barriers, but also by non-allopatric factors such as natural sel ...

Abstract:
... The recovery goal for the jaguar Panthera onca in the USA should be to restore significant presence with some reproduction, consistent with historical records. Nevertheless, the prevailing conservation strategy for the jaguar does not include restoration in peripheral range and merely seeks long-term survival of the jaguar within its existing northern range, which is almost entirely in Mexico.
